To all whom it mag concern:

Be it known that L- anus-tun E. Simon, of Lowell, in the county of ll/ilClCllBSQXflHCl State of lviassachusetts, a citizen of the l'lnitcd States, have invented a new andtiseful Improvement in BeamvVarpers, of 'which the following is a full, clear, and

exact description, reference being had to the accompanying drawings, forminga part of this specification, in explaining its nature. v The present invention relates to a bea attachment or device for steadying the beam of the war-per while filling.

As is well known to those skilled in the 7 art, a war-per beam is supported to have not only a rotary"movement froin a driving drum but also movement relatively to the drum by reason of the accumulation and increase of yarn upon the beam which tends to move the beam away from the drum. At the beginning of the wind when the beam has little yarn upon it, it has little weight and accordingly cannotnbear against the cylinder with sufficient pressure to run steadily. Asthe beam fills with yarn its weight increases which assists in maintaiir ing it in proper contact with the driving cylinder, but until the beam becomes substantially filled with yarn it does not have sufiicient weight to bear properly against "the driving cylinder unless the beam is subjected to some steadying influence.

It is accordingly the'object of my invention to provide the beam with an attachment or device which will exert such steady ing influence and one, moreover, gradually diminishing in its intensity as the beam increases in weight by the'increase of-yarn upon it.

My invention can best be seen and understood by reference to the drawings in which I have shown an embodiment thereof applied to one side of a warpensuch portion thereof only being shown as is necessary to illustrate my invention, in which connection it will be understood that the same devices for supporting and controlling the beam are employed at both ends thereof on either side of the machine.

Figure 1 is a side elevation. Fig. 2 is 7 also a side elevation showing a changed disposition and adaptability of the device forming the subject-matter of my invention, Fig. 3 is a front elevation of a detail of construction to which special reference will hereinafter be made.

fieferring to the draw1ngs:l represents a portion of the frame at one side of the we, r ping machine.

' 2 is the beam; 3 the flange-forming ends of the beam; a the beam shaft; 5 the driving cylinder or drum which is shown in dotted lines in Figs/1 and 2, that the position of the beam and its support with relation thereto may be determined.

The beam is shownhaving a new and improved type of support which I have adopted for purposes of illustration inasmuch as my present device or attachment eiiicicntly cooperates therewith in the control of the beann In this connection 6 is a. supporting arm which is pivoted to the interior side or face of the frame 1 by means of an" inwardlyprojecting stud 7 on which the arm turns. The arm 6 has secured to it a quadrant- S which forms preferably integral connection with the arm and turns with it upon the stud 7. The outer edge of this quadrant is toothed and engaging it is a. pinion, 9 operated by any suitable mechanism (not, shown) and by which the quadrant may be turned and the arm with it, or be maintained in any adjusted position. When the machine is in operation the arm is maintained in an upwardly-inclmed engaging position substantially as nal position.

Mounted upon the arm 6 is a sliding block 10 havinga bearing 11 for the projecting end of the beam shaft and in which this shaft turns. The block is secured to the arm to slide longitudinally over the-top surface thereof as the beam is moved away from the driving cylinder by the accumulation and increase of yarn upon it. Secured to the outer end of the arm is a stop 13 which prevents the block sliding off theend of the arm.

Secured to the frame adjacent the outer side thereof is an arm 15. This arm is pivotally secured to the frame by a stud 16' which lies below and just back of the beam latch 20 by which the arm 15 may be held,

in a-raised or disengaging position with relation to the beam shaft, substantially as shown in Fig. 2,-or be released to a position of: engagement withsaid shaft, as above described.

The latch 20 consists simply of a leve r pivoted by. a pin 21tto the bifurcated end 22 of the stud"? supporting the arm ,6 and which projects beyond the outer face of the frame. Thestructural arrangement of the latch or lever 20 is such that it may be turned to assume an engaging or disengaging position with relation to the finger. The engaging position is secured by turning down the latch when the finger will engage I and rest upon the outer-end thereof and in which position the latch is maintained by the bearing of the end 23 of the latch against the outer end of the stud (see Fig. 3). From this engaging position the latch maybe turned to a disengaging position with relationto the finger simply by raising bea-1n,=theibeam shaft :and .a support 1 for I said --shaft =withrelation to which support said shaft may have combined movements of rotation and inward or outward translation, 40f aset ofbent levers fulcrumed below said shaft and extending upwardly to {extend over,a'nd :rest upon-the endsof-said shaft the arm 15 after which this arm.:may be lowered to engage the beam shaft as aforesaid.

The operation is as follows: When the beam is empty or substantially empty at the beginning-of the wind the weighted arm .15

resting upon the beam shaft will-operateto exert considerable pressure for holding down the shaft upon its :supporting'bearing and insuring cooperation between the drumand the driving cylinder. As thebeam lil l si it inovesoutwa'rd longitudinally of its support and the weighted arm will acc'ordinglybear against the beam shaft with a gradually decreasing degree ofpressureythe pressure of the arm, -1I1-0tl1e1"?WO1dS, de-

-crea'sing astheiweight ofithe beam increases. I In practice the disposition and :arrangement of the weighted arm 15 is such'that it will exert a leverage of about 7 :1 upon the shaft of an empty beam, wh il'e --u-ponthe completion -ofthe filling of the beam; the leverage will have decreased to about 1: 1. After the beam has become filled and it is desired to dislodge the same from the machine by the turning down of the arm 6 through the operation of-the quadrant as aforesaid, or

when the weight of the yarn becomes sufficiently great tOyQliIIIiIIittB the need of additional pressure,the arm 15-is raised into a position of disengagement, asshown-in Fig.

.2, and held in this ,position by the latch.

After afresh beam has been placed in the vmachinethe latch is released and the-arm lowered into engagement with the beam shaft, and'the operation proceeds as before.

Having thus fully described my invention, Iclaim' and desiretosecure by Letters Patent .of the United States 1.
